County coverage
North Carolina counties keep the deeper score: address points, parcels, jobs, facilities, NPI practices, and exempt organizations. Every other county shows the layers loaded for it. County boundaries are 2025 TIGER. Housing totals are ACS 2019–2023. Public schools are NCES 2024–25. Address points outside a parcel roll are the National Address Database compiled June 30, 2026, where a state submitted them.
